Still cares: The facility where the 36-year-old former NBA star will continue his recovery is close to estranged wife Khloe Kardashian's Calabasas home just outside LA. They're pictured together in 2012

The rehab facility is located near to Khloe's home in Calabasas, just to the west of LA, so she'll be able to visit and keep an eye on his ongoing care.

The 31-year-old reality star called off her divorce when she heard of the former NBA star's collapse, so that, as next of kin, she could make medical decisions on his behalf.

While she declined to give any more details about Lamar's condition during an interview for her new FYI show Kocktails With Khloe, it's believed he is still unable to walk unaided and has suffered kidney damage as well as problems with speech and cognitive function.

'At the center, Lamar will continue to receive amazing therapy. He still has many challenges but is making progress,' an insider told People. 'He is a fighter!'

Medical emergency: Lamar collapsed from a drugs overdose at a Nevada brothel in October and spent four days in a coma at a Las Vegas hospital before being airlifted to Cedars-Sinai Medical Center in Los Angeles

Lamar spent four days in a coma after a near fatal overdose of opiates and cocaine as the Kardashian and Jenner families gathered at his bedside.

Once he regained consciousness, Khloe had him airlifted to Cedars-Sinai Medical Center in Los Angeles where he has remained ever since.

In addition to Khloe, Lamar's children Lamar Jr., 13, and Destiny, 17, visited him over the holidays, flying in from New York where they live with their mother Liza Morales.

Lamar Jr. posted a selfie with his dad and sister with the caption: 'Christmas with my pops. Here's to 2016. Blessed.'

Only half of the ex-athlete's face could be seen in the photo.

Family support: In addition to Khloe, Lamar's daughter, 17, and son, 13, visited their dad over the Christmas holidays, flying in from New York where they live with their mother Liza Morales

While Khloe has rekindled her relationship with boyfriend James Harden, seeing in the New Year with the Houston Rockets star in Texas, she has pledged to support her ex through what remains a long road to recovery.

But she's also made it clear that it's up to him to focus on his health and well-being.

'He has to walk that road by himself, and, most importantly, he has to want to walk that road. I will be there supporting him every step of the way,' she previously told People.
